As an advanced welding method, laser welding machine has been applied in all walks of life. In the use of laser welding machine, there are always some large and small failures. The following is a summary of laser welding machine common failures and solutions.

Fault one, the laser welding machine screen is in the black screen state

There is something wrong with the screen of laser welding machine, find out the reason in time, repair or replace the screen.

Fault two, laser welding machine welding penetration is not enough

1) insufficient laser energy can be solved by increasing pulse width and current.

2) the defocusing amount of the focusing mirror is not correct, so the defocusing amount should be adjusted to the position close to the focus (but no spatter).

Fault three, laser welding machine in the use of the process of the main machine in a shaking state

Laser welding machine under the foot base is not fixed, or only fixed part of the solution: the laser welding machine base can be fixed

Fault four, when the laser welding machine welding workpiece crack

1) the protection gas flow rate is too large, can reduce the protection gas flow rate to solve.

2) the cooling speed of the workpiece is too fast, the cooling water temperature on the fixture should be adjusted to improve the water temperature.

3) the workpiece is not cleaned. In this case, the workpiece needs to be cleaned again.

4) the matching gap between the workpiece is too large or burr, should improve the machining accuracy of the workpiece.

Failure five, laser welding machine welding flame weakened

1) main optical path laser migration, solution: adjust the main optical path full reverse and half reverse diaphragm, using imaging paper to check and round the spot.

2) cooling water pollution or long-term failure to replace the cooling water, solution: replace the cooling water and clean the filter uv glass tube and xenon lamp.

3) the resonant cavity diaphragm of the focusing lens or laser is damaged or contaminated. Solution: replace or clean the focusing lens and resonant cavity reflection diaphragm.

4) the laser is not output from the center of the copper nozzle under the focusing head. Solution: adjust the 45 degree reflection diaphragm to make the laser output from the center of the nozzle.

5) the light brake does not spring off completely. Solution: check and add lubricating oil on the light brake connector to make the connector mechanically smooth.

6) the protection gas is opened too much, the solution: adjust the protection gas flow rate.

Fault six, laser welding machine welding seam is very black

1) the airflow direction of the protection gas is wrong, solution: make the airflow direction of the protection gas and the movement direction of the workpiece opposite.

2) nitrogen is not on, solution: turn on nitrogen.

In addition to the above six kinds of laser welding machine common faults, there are many other faults, when the laser welding machine operators can not deal with the fault, should contact the manufacturer in time to solve. Chuyuan laser welding machine 24h after-sales response, 3d problem solving, is the industry's leading after-sales service. Select laser welding machine, identify xinrui laser.
